Heat Treatments Control Sprouting and Rooting of Garlic Cloves

  Hot water dips (45 - 60 ºC for 2.5 - 60 min) were evaluated as potential treatments to reduce sprout and root growth in peeled or unpeeled cloves in which sprouts had begun internal development but not yet emerged. Water dips at ≤ 50 ºC did not reduce sprout and adventitious...

Quality changes and respiration rates of fresh-cut sunchoke tubers (Helianthus tuberosus L.)

  Changes in quality attributes (discoloration, surface dehydration, translucency, color values, texture), respiration, phenolics and phenylalanine ammonia lyase (PAL) and polyphenol oxidase activities of sunchoke tuber slices were studied at 0, 5 and 10C. Cleanly cut smooth surfaces had less...

Cutting Blade Sharpness Affects Appearance and Other Quality Attributes of Fresh-cut Cantaloupe Melon

  Cantaloupe melon pieces (1.8 cm dia x 3.5 to 4.0 cm cylinders) were prepared using stainless steel borers with sharp or blunt blades, and stored for 12 d in air at 5 °C. Pieces prepared with the sharp borer maintained marketable visual quality for at least 6 d, while those prepared with...

Postharvest management of New Zealand flower thrips (Thrips obscuratus) on apricots using ethyl formate or pyrethrum-based treatments

New Zealand flower thrips (NZFT, Thrips obscuratus (Crawford)) were exposed to a range of ethyl formate (EF) and pyrethrum-based postharvest treatments on apricots. Research showed that EF+CO2 or EF+N2 were effective treatments against NZFT and caused negligible damage to apricot fruit quality....

Postharvest Cooling and Handling of Peppers

The preferred temperature range for peppers is from 45 to 50 °F. Since pepper harvesting in North Carolina normally occurs during the hottest months of the year, it is not unusual for the pulp temperature of harvested peppers to be more than 90°F. If they are allowed to remain at high...

Manual de manejo cosecha y poscosecha de granadilla

El carácter climatérico de la fruta es importante para determinar el manejo poscosecha, pues las frutas climatéricas son en general más susceptibles al deterioro dada su alta sensibilidad a condiciones ambientales tales como la presencia del gas etileno. Las frutas...

Quality changes in fresh-cut pear slices as affected by controlled atmospheres and chemical preservatives

  Low O2 (0.25 or 0.5 kPa) elevated CO2 (air enriched with 5, 10 or 20 kPa CO2), or superatmospheric O2 (40, 60, or 80 kPa) atmospheres alone did not effectively prevent cut surface browning or softening of fresh-cut pear slices. A post-cutting dip of 2% (w/v) ascorbic acid, 1% (w/v) calcium...

Postharvest Cooling and Handling of Strawberries

Strawberries are extremely perishable and have unusually demanding postharvest handling requirements. Even under ideal conditions they can rarely be kept for more than 7 days after harvest. They must be cooled immediately to their lowest safe temperature (32 to 34 F) to prevent overripening and...
